[Arch Linux] Hiddify Next TUN Mode Troubleshooting Guide (AppImage, AUR, TUN conflicts)

[im-Qarch]

Hi Hiddify team and community

I recently tried to run Hiddify Next TUN mode on Arch Linux (Garuda Linux i3) and faced several issues during setup.

The main problems were:

• Flutter AppImage rendering problems (GPU/Vulkan related)
• switching from AppImage to native AUR package
• TUN mode permission issues
• KDE/system proxy configuration failures
• conflicts with other TUN based applications like Nekoray/sing-box
• routing rules and nftables conflicts

After troubleshooting, I created a step-by-step guide documenting the complete process:

Gist:

Environment tested:

• Arch Linux
• Garuda Linux (i3 WM)
• Hiddify Next 4.x
• sing-box core

The goal is not to replace official documentation, but to help Arch Linux users quickly identify common issues and avoid spending hours debugging.

If this information is useful, maybe parts of it could be added to the official Linux documentation or troubleshooting section.

Thanks for building Hiddify ❤️
